The well is located about 300m updip from Kangaroo-1 and will test a thick reservoir sequence observed in all surrounding wells. Karoon expects to penetrate the top of the reservoir section within approximately three weeks, with the well reaching total depth in December 2014, using the Olinda Star semisubmersible drilling rig.
The company says that the appraisal well is designed to confirm the size of the oil column, the presence and size of a possible gas cap, reservoir continuity and properties, and flow rates for the Kangaroo oil discovery. The information will be crucial to Karoon to assess the commerciality of the Kangaroo oil field and, if successful, will be the basis for the front end engineering and design (FEED) phase bringing the project a step closer to being commercial.
Karoon announced its drilling campaign plans in October, in which the company stated two to four appraisal and exploration wells will be drilled the month. The Karoon-operated wells, S-M-1037, S-M-1101, S-M-1102, S-M-1165 and S-M-1166, are all located in the Santos basin and will be drilled using the Olinda Star for the entire campaign, which is expected to continue into 1H 2015.
The rig contract provides Karoon with two firm wells plus two option wells, providing maximum flexibility for further appraisal of the Kangaroo oil discovery, including testing and appraisal of the Kangaroo West prospect in the event of a successful drilling in the first two wells.
The second well in the program is the Kangaroo West-1 exploration well. Due to the large size and proximity to Kangaroo, a successful outcome at Kangaroo West-1 would materially add to any possible development of the Kangaroo oil field. The play type for Kangaroo West-1 is proven at Kangaroo-1 with the intersection of a 76m gross oil column and oil recovered to surface from wireline DSTs.
Kangaroo West-1 is located on the western flank of the same salt structure as Kangaroo-1 and has the same trap type and reservoir and seal intervals that have been mapped into the prospect from surrounding wells.
Karoon is in a joint venture with Pacific Rubiales Energy Corp. (35%) in the five wells.
